amazon-web-services - 如何从命令行复制 ec2 "launch more like this"？

Question

aws ec2 界面有一个名为“launch more like this”的按钮，可启动第二个实例(如所选实例)。据我所知，aws 命令行界面中没有类似的功能。

这是一种将实例构建为另一个实例的副本的有效方法(尽管有些拙劣):

function cloneinstance {
  awsinstanceid=$1
  region=$2
  export AWS_DEFAULT_REGION=$region
  ami=$(aws ec2 describe-instances --instance-ids $awsinstanceid | grep INSTANCES | awk '{print $7}')
  privatekey=$(aws ec2 describe-instances --instance-ids $awsinstanceid | grep INSTANCES | awk '{print $10}')
  securitygroup=$(aws ec2 describe-instances --instance-ids $awsinstanceid | grep SECURITYGROUPS | awk '{print $2}')
  instancetype=$(aws ec2 describe-instances --instance-ids $awsinstanceid | grep INSTANCES | awk '{print $9}')
  subnet=$(aws ec2 describe-instances --instance-ids $awsinstanceid | grep NETWORKINTERFACES | awk '{print $9}')

  awsinstancedata=$(aws ec2 run-instances --image-id $ami --key-name $privatekey --security-group-ids $securitygroup --instance-type $instancetype --subnet-id $subnet)
  awsinstanceid=$(echo $awsinstancedata | awk '{print $9}')

  # AWS CLI sucks and doesn't return error codes so have to look for a valid id
  if [[ "$awsinstanceid" == i-* ]]; then echo -e "\t\tSuccessfully created. Instance ID: $awsinstanceid"; else echo -e "\t\tSomething went wrong. Check your configuration."; exit 1; fi 
  echo -e "\t\tWaiting for it to come up..."
  aws ec2 wait instance-running --instance-ids $awsinstanceid
  echo -e "\t\tServer is up and ready"
}
